UNIVERSAL WATCH.

SPECIFICATION forming part of Letters Patent No. 345,406, dated July 13, 1886.

A pplicution lcd October 5, 1885.

To all whom t may concern:

Be it known that I, LEOPOLD BGUELTN, of Tramelan, in the Canton of Bern, Switzerland, have invented a new and useful Improvement iu Universal lVatches, of which the following is a specication.

Universal watches and clocks have been i made heretofore vfor indicating the time of different cities. Universal clocks have also been made for denoting the time of places in connection with their degree of longitude.

My invention relates to a watch in which are pairs of moving and stationary dials, upon which are marked hours and minutes and names of places. Upon one side ofthe watch is an outer stationary ring-dial, upon which hours and minutes are marked, and within this ring-dial is a moving and, preferably,vari colored dial divided into twelve or twentyfour equal spaces corresponding with the hours upon the outer dial, and marked with the names of different cities, and upon the other sidc of the watch is an outer stationary ringdial, upon which are marked the names of the same places, preferably in different colors, and within this dial is a moving dial divided into minutes. lllhese parts are operated by the usual train oi` gearing and movements of a watch.

My improvements are employed in connection with watch-works of any ordinary character, the dial-work heilig alone of a special construction.

In the drawings, Figure l is a vertical section of the watch, in which l have illustrated only the mechanism necessary for operating my improved devices. Fig. 2 is an elevation of the twelve-hour-dial watch, the hands, and name-dial. Fig. 3 is an elevation of the opposite dial, for indicating the time in units. Fig. 4 represents separately the movable name dial of the twelve'hour face, and Fig. 5 the movable minute-dial from the center of the namedial, Fig. 3. Fig. 6 is an elevation of the twenty-tour-hour-dial watch. Fig. 7 represents the opposite side and dial ot' the same watch. Fig. 8 shows the movable dial from within the twenty-four-hour dial of Fig. 6, and Fig. 9 the movable niinutedial from within the name-dial shown in Fig. 7.

In all the figures the same letters of reference denote the same parts.

Serial No. 179,062. (No model.)

The manner of determining the time of various places in my improved watch is as follows: The face ofthe watch, Figs. 2 and 6, shows a ring-shaped dial, A, iixed on the plate ofthe case, the same being divided into twelve or twenty-four hours, and into minutes upon the outer part of the ring, and upon the inner edge, between each hour-mark, there are twelve divisions on the twelve-hour dial, and six divisions on the twenty-four-hour dial. Upon this dial a certain local time is shown by an hour-hand, B, and a minute-hand. C, similar to common watches. lVithin or behind the opening of the dial Ais a movable dial,D, fixed, by means of clamp-nuts E and F, to a tubular sleeve upon the hour-wheel G, which bears the hand B. and which surrounds the tubular sleeve upon the cannon-pinion- The movable dialD is divided into twelve equal parts in Fig. 2, and twenty-four equal parts Fic. 6, and represents geographical hours, and these divisions are radial upon the dial D, starting from the Green wich meridian. (Shown by a special line.) Every segment or radial division of the dial D representing a geographical hour should receive a distinct and special color from the divisions at each side of it, and upon these divisions are placed the names of towns or cities whose time it is desirable to indicate, and the time is easily read and distinguished, because of the vari-colored spaces. The same colors should be repeated six geographical hours distant from each other, so as to avoid any con fusion. rlhe dialD is inscribed with the names of various cities according to their location, either east or west of the Greenwich meridian, and according to such location the names are inscribed upon the dial D representing their geographical hour, and alongside of each name is a line to the periphery of the dial D, the position of which line in relation to thc divisions upon the inner portion of the dial Aindicates the hour, and within live minutes of its time, upon the twelvehour dial, and shows the hour, and within ten minutes of its time, uponthetwenty-four-hourdialoftheparticular city whose time it is sought to ascertain. The back or opposite side of the watch carries a ring-shaped fixed dial, H, secured on a circle, H', and snapped upon the cased-ing in the usual manner. The names of the cities inscribed on the movable dial D are repeated on the dial IOO H, and the same colors are usedfor the names of said cities on the dial H as are preferably used for the geographical -hour segment to which they belong; but they are placed in the order corresponding to their geographical minute, starting from the Greenwich meridian. The ring-shaped dial H, on account of itslarger size, may also bear inscribed upon it the names of other important towns which could not be placed on the movable dial D. The color with which the names of those towns are inscribed on the dial H corresponds with the colors of the geographical-hour division upon the dial D to which it belongs, and this manner of grouping colors'has been adopted to prevent confusion and to easily distinguish the segments and citiesthat belong in the same geographical hours. dial H is a` second movable dial, I, x'ed by means of screw-nuts-K and L to the arbor M of the minute-hand G. There is a toothed wheel, N, also mounted upon this arbor M, and said wheel meshes with the teeth' of the wheels in the usual train of gearing The movabledial I is marked with divisions into sixty minutes, and itturns simultaneously with the minute-hand, and its divisions in relation to the radial lines to the names of the cities upon the dial H indicate the exact minute of time at the city whose time is being ascertained.

To read the exact time of any city on the watch having twelve hours, (Figs. 2 and 3,) St. Petersburg, for instance, will. be found on dial D, Fig. 2, on the line between two oelock and two hours and tive minutes ofthe inner division of dial A. Bylooking at the reverse side of the watch it will be found, then, that the line of St. Petersburg on the dial H is in front of the rst minute-division of dial I, so that the watch shows for St.

Petersburg that exact time is two hours onel minute when the meridian on the dial corl'csponds to twelve noon. Now, if we want to know, for instance, the right Paris time by the dials of the twenty-four-hour watch, we find in Fig. 6 of the drawings that the line from the name Paris in the geographicalhour segment in which Paris is inscribed (colored in blue, for instance) is placed be'- tween the XII and the I hour-mark, and between the first and second mark under XII. Then we lind immediately on the other side of the watch that the line corresponding to Paris on the dial H is placed in front `of the ninth minute-division of the moving dial I, that shows for the exact time of Paris twelve hours nine minutes, thus indicating that when it is twelve oclock on the Greenwich meridian it is nine minutes past twelve in the city of Paris. The moving dial D bears in a blue segment, for instance, the names of Paris, Berne, and Berlin, and upon the dial H, I inscribein the same blue color the names of the towns of Bruxelles, Amsterdam, Co-

' inbefore described.

In the opening of this iixed logne', Carlsruhe, Stuttgart, Milan, Hambourg, Ghristiania, Munich. Rome, Copenhagen, Trieste, and Prague, Fig. 7. cidence in colors ofthe segments or the names of these cities on the dial Hwith the segment of corresponding 4color upon the dial D containing the lnames of Paris, Berne, and Berlin, is done to indicate that the longitude of those places is between that of Paris and Berlin, and that necessarily their geographical time is between that of those two places, the exact geographical time west of the Greenwich meridian being found by the means here- The names' found on the right-hand side ofvdial H, Fig. 7-viz., Bruxelles, Amsterdam, and Cologne-belong to the rst half of the geographical hour in question, while those written on the left-hand side ot' the dial H-viz., Garlsruhe, Munich, Rome, Copenhagen,- Trieste, and Prague-belong to the second halfofthe same geographical hour. The geographical minute of the other cities upon the dials can be found in the same way as hereinbefore described by observing the hour and minute position of the name of the town on the dial H in regard to the eXactminute-division of the moving dial I.

I do not claim a moving dial within a fixed dial.

In my improvement the colors on the mo ing dial facilitate the recognition of the hou marks on the said moving dial.

I claim as my invention- 1. In a watch or clock, the combination of as set forth.

2. The combination, in a watch'or clock, with the fixed dial A and moving dial D, as set forth, of the fixed dial H upon the reverse side of the watch, and upon whose face IIO are indicated names of cities corresponding with those on the dial D, and a moving dial, Lwhose face is divided olf into sixty minutes,

as and foil the purposes speciiied. l

3. The combination, in watch or clock,with

the fixed dials A andv H, constructed as speci tied, ofa moving dial, D, formed with radialvari-colored segments upon its face, and connected to the sleeve of the wheel moving the hour-hand B, and the minute-dial I upon the reverse side of the time-piece and connected Yto the arbor of the minute-hand C, as and for the purposes set forth.
